Imaging with extra-narrowband filters is the latest technique used by amateur astronomers for producing striking, high-contrast color CCD astro-images of emission nebulas. These specialized "line" filters transmit only the specific wavelengths of light important in emission nebulas, while blocking out all the rest. Orion's new set of 2" filters consists of an Orion Hydrogen-alpha, an Oxygen-III, and a Sulfur-II filter. These narrowband filters have a full-width half maximum (FWHM) bandpass of just 7nm, ensuring high-contrast images, even in heavily light-polluted or brightly moonlit skies. The filters can be used separately or in combination with a filter wheel for advanced tri-color imaging of emission nebulae. They're ideal for use with monochrome CCD cameras.
So if you're ready to go beyond LRGB imaging and capture your favorite nebulas in a revealing new light - no matter how light-polluted your skies - add our Extra-Narrowband CCD Imaging Filter Set to your imaging repertoire! Includes a protective plastic case for each filter.
